From: Mathieu Desnoyers Date: Tue, 20 Dec 2011 18:12:30 +0000 (-0500) Subject: Rename sessiond internal "uid" fields to "id" X-Git-Tag: v2.0-pre16~13 X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=a991f516ac2783c833ebbc6ac0ac3c0e4ca71371 Rename sessiond internal "uid" fields to "id" Ensure we don't confuse "user ID" (UID) and session unique ID (session_id or id).
